Yes, you should make labels for your quilts. You always think you will remember when they were made but that doesn't happen. All artists sign their works and so should you. I use the lettering built into my machine - one of these days I will master setting the labels up in the embroidery program and sending them to the machine. Some people use permanent markers to write out their labels. Whatever way you chose just be sure you do it. It will be appreciated down the road!
